What is the sum of the first eight terms of the series? (−600)+(−300)+(−150)+(−75)+(−37.5)+ round the answer to two decimal places. −1200.50 −1195.31 −1190.63 −1181.25

The given sequence is a geometric series.

Common ratio can be found as :

(-300/-600) = 0.5

(-150/-300) =0.5

So common ratio is 0.5

First term is -600

The attachment shows the required calculations.

Sum of eight terms is (-1195.31).

x/3-10=8

x/3=18

x=48

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
